You can manage the list of resource plans through the Resource Plans property sheet. As you know by now, you can use resource plans to allocate resources among consumer groups. The Resource Plans property sheet lets you create, delete, and modify the settings of a resource plan. To manage a resource plan, go to Database Control Home Page Administration Consumer Groups. From the Object_Type drop-down window, select Resource Plans. The Resource Plans page appears, with a listing of all the current resource plans. You can either create a new resource plan or select a resource plan from the list.

Once you create users in the database, you need to control their access to the various data objects. To take a simple example, a clerk in the human resources department of an organization may be able to see the salary data of employees, but he or she should not have the authority to change salaries. Oracle uses several means to control data access, and the most elementary way to do so is by assigning database privileges and roles to database users.

A privilege is the right to execute a particular type of SQL statement or to access a database object owned by another user. In an Oracle database, you must explicitly grant a user privileges to perform any activity, including connecting to a database or selecting, modifying, and updating data in a table other than their own. There are two basic types of Oracle privileges: system privileges and object privileges. You use the GRANT statement to grant specific system privileges as well as object privileges to users. The following sections cover these two types of Oracle privileges in detail.

You can manage your users through Database Control by going to Database Control Home Page Administration Users (under the Users and Privileges Section).
System Privileges
You grant a system privilege to a user so the user can either perform a particular action within the database, or perform an action on any schema object of a particular type. A good example of the first type of system privilege is the privilege that lets you connect to a database, called the CONNECT privilege. Other such system privileges include the CREATE TABLESPACE, CREATE USER, DROP USER, and ALTER USER privileges. The second class of system privileges grants users the right to perform operations that affect objects in any schema. Examples of this type of system privilege
CHAPTER 11 USER MANAGEMENT AND DATABASE SECURITY
include ANALYZE ANY TABLE, GRANT ANY PRIVILEGE, INSERT ANY TABLE, GRANT ANY PRIVILEGE, INSERT ANY TABLE, DELETE ANY TABLE, and so on. As you can see, system privileges are very powerful, and granting them to the wrong user could have a devastating impact on your database. Here are some common system privileges in an Oracle database: ADVISOR ALTER DATABASE ALTER SYSTEM AUDIT SYSTEM CREATE DATABASE LINK CREATE TABLE CREATE ANY INDEX CREATE SESSION CREATE TABLESPACE CREATE USER DROP USER INSERT ANY TABLE
Granting System Privileges
You use the GRANT statement to grant system privileges to users. When you grant a system privilege to a user, the user can immediately use that privilege. Thus, privileges work in a dynamic fashion.
Tip
You can use either Oracle Enterprise Manager Database Control or SQL statements to GRANT and REVOKE system privileges.
For example, to grant the CREATE SESSION system privilege to the sample user, hr, allowing hr to log on to an Oracle database, issue the following statement: SQL> GRANT CREATE SESSION TO hr; Grant succeeded. SQL> The CREATE SESSION privilege enables a user to log on to an Oracle database.
